Operation Principle
1) Power supply detecting
The power supply detecting board of the emergency equipment K11 inspects the status of the input three phase
power supply all the time.
If the power supply is in normal status, the storage battery set of the equipment is
automatically floating charged by charging loop and be kept at the rated work voltage.
The charging loop has
over-charge, over-current and short-circuit protecting functions. If the power of the loop is off, a power off signal
will be sent to the controlling system and the system will make emergent processing.
2) Emergent operation
The controlling system of the ARD will immediately detect the status of the elevator and automatically start the
emergent rescue when the elevator runs into a power failure (for type G and S) or a controlling system fault of the
elevator (for type H and HB). First the power supply contactor K12 is pulled in, the connection between the R, S,
T three-phrase controlling power supply and the inputting terminals R0, S0, T0 of the controlling power supply in
the elevator’s controlling cabinet is shut off by the normally-closed contacts.
relay K3 closes.
Then the safety, lock and
The normally opened contact of
overhaul loops of the elevator are detected, and the door area
sensor is powered on, the near floor signal is also detected.
If the loops are in normal status the converter will be
switched on to power on the door machine controlling system.
The relay K14 of the ARD is pulled in (see
picture 8 for AC door machine, see picture 9 for DC door machine, and see picture 10 for variable frequency door
machine), the door-motor MD gets the voltage it needs, and opens the car door and landing door synchronously.
If the cage is not at the near floor position, the normally opened contacts of brake relay K7 and K8 close (see
picture 11), the DC converter supplies the brake loop to open the brake.
The voltage outputted from 3-phase
reversing loop goes through K10’s normally opened contactor (which is closed now) to power on the traction
machine, which pulls the cage to run at a certain direction.
The cage moves to the near floor position and stops.
The 3-phase reversing voltage stops outputting, the brake closes. After the car door and cage door are opened, the
6
Sh an g hai Wens h an g
WS420 ARD
contacts of contactors and relays of the ARD mentioned above resume to the status before the emergent operation.
The connection between 3-phase AC power supply and the controlling system of the elevator is resumed and the
emergent operation is ended, the power supply of the ARD is automatically shut off.
3) Safety lock
If the controlling system of the ARD judges the stopping of the elevator is due to the fault of safety loop or door
lock loop, the equipment will not start the emergent operation according to the requirements of Safety Norm for the
operation of elevator. After the emergent operation is started, the ARD still detects the signal from elevator safety
loop and door lock loop all the time.
Once a protecting signal is generated, the emergent operation is stopped
immediately to assure the safety of the passengers and the elevator equipment. At the mean time the ARD is also
detecting the overhaul loop of the elevator’s controlling system all the time.
When the service personnel are
examining the elevator, the ARD is automatically locked and will not be put into emergent operation if only the
examining switch is pressed down.
4) After the emergent operation
Installation
Wiringis
After the emergent operation, the connection between the equipment and the controlling
system ofand
the elevator
shut off and the ARD is at the isolated stand-by status without any affection to the operating of the elevator.
The elevator can normally operate if only the power from the 3-phase AC power supply is resumed. The charging
loop of the ARD automatically charges the storage battery set again.
3.
Installing Connection
The ARD is easy to install. If there is a machine room it can be installed beside the elevator controlling cabinet;
if there is not a machine room, it can also be fixed beside the controlling cabinet with the accessory installation
rack. Before starting connection the personnel shall first open the shell of the ARD’s host machine and take out
the controlling cables and relays, as well as other accessories. The general connection between the ARD and the
controlling system of the elevator is shown in picture 5.
This user’s manual is a unified general version to match all types of elevators produced inside/outside China
instead of a special version for a certain elevator. When you get this manual, please do not be hurry to connect
those wires. We suggest you carefully compare the drawings in this manual with corresponding drawings of the
elevator’s controlling system, find out the corresponding signal or terminal numbers needed for connecting with
the ARD on the drawings and make marks. A signal-comparison-table (for signals related with the ARD and the
elevator’s controlling cabinet) is strongly recommended for the using of connection. If other drawings or
supplementary text illustrations are appended to the manual, it is due to the special requirements of your elevator.
Please take these appended drawings and supplementary text illustrations as the criterion for installation and
debugging.
1) Connection of main power supply
For most elevators, the terminals B3-1, 2, 3, 4 (R, S, T, N) shall be connected to the R, S, T and N terminals of the
3-phase power supply of the elevator’s controlling cabinet (Note: Be careful not to connect the zero line N to the

6 terminals of the ARD.
That is, make the ARD, the 3-phase AC power supply and the 380V controlling
transformer a series connection, and then connect U, V, W terminals of the ARD to the 3-phase output power
supply terminals U, V and W between the controlling cabinet and the traction in a parallel connection with
4~6mm2 cables. (The wires, backup-traveling cables shall be prepared by the user)
2) Connection of storage battery set
The connection between the ARD’s host machine and the storage battery set is prepared at the host machine end.
The user needs to take out the connecting cable and connect them to corresponding terminal posts of the battery
set separately (see picture 4).
The red post is anode and the black one is cathode. (For ARD for elevators

2) Checking connection
Please check the connections one by one carefully following the elevator’s electric controlling drawing and the
drawings provided in this manual, special attention shall be paid. The power supply lines cannot be connected to
input/output signal terminals! The B1, B2 and B3 plugs cannot be plugged into wrong place! Otherwise the
equipment may be damaged! After all drawings, parameters, logics and connections are confirmed to be correct,
please follow the following procedures to debug.
3) Debugging the status of safety, door lock and overhauling loops
Unplug the B1 plug from the ARD; use the resistance grade of the multi-meter to measure the safety loop
between cable B1-1 and B1-2. When all switches in the loop are closed, the status of the loop shall be “PASS”.
If any switch component is cut off, for instance, the cage emergent stop button is pressed down (Note: the
emergent stop button on the controlling cabinet is not in the checking loop of the ARD), the status between B1-1
and B2-2 shall be “BROKEN”.
Use the same method to check the door lock loop between B1-5 and B1-6.
When all doors are closed the status shall be “PASS”. Open any landing door or car door the status shall be
“BROKEN”.
To check the overhauling loop between B1-9 and B1-10, when there is no overhauling, the status
shall be “PASS” (it depends on the overhauling logic level of the elevator, the status may also be “PASS” when
there is an overhauling). Press down the overhauling button, the status shall be “B ROKEN”. After checking the
plug shall be plugged into the socket.
4) Check the input signal from the elevator to the ARD
Put the power supply switch on the front panel of ARD to OFF position, the elevator shall be able to operate
normally.
Otherwise the connections of safety loop, door lock loop and overhauling loop between the elevator
and the ARD plug shall be checked to see whether they’re correct.
5) Checking the ARD
ARD’’s power supply
16
Sh an g hai Wens h an g
WS420 ARD
Procedure
If the elevator can operate normally, stop the elevator at the near floor position, shutCommission
off the 63A breaker
in the
ARD, and then put the switch on the front panel of ARD on the “ON” position, thereafter power on the 3-phase
AC power supply to check whether the power supply is in normal status. If the power supply is in normal status,
the red power supply indicating lamp on the front panel of the ARD is on, and the X1 lamp of PLC is on, after 10
seconds of delay, the Y0 indicating lamp is on, then the following debugging can be made.
6) Checking the logic movement at the near floor position
Shut off the 3-phase AC power supply first, if the landing door and car door are closed, the indicating lamp of
PLC’s safety loop’s signal input point X2 , the indicating lamp of PLC’s door lock loop’s signal input point X3,
and the indicating lamp of PLC’s overhauling loop’s signal input point X4 (all three loops are in the ARD) are all
on.
And the indicting lamps of PLC’s switching output point Y2, detecting output point Y3 and opening door
output point Y5 are also on.
If the landing door and car door are open, there is not output at Y5 and the lamp is
not on. If the near floor sensor is valid for low level (e.g. magnetic switch), the lamp at input point X5 for PLC’s
door area signal shall be on. (which is not on at standing by) If the near floor sensor is valid for high level (e.g.
photoelectric switch), the output of the sensor is 24V, then the PLC’s input point X5 shall be shut off and the
indicating lamp shall not be on. (the lamp is always on at standing by) For these two scenarios, the green
indicating lamp LED on the front panel of the ARD shall be on.
Note: The elevator shall not be at overhauling status; otherwise the ARD will not act. If the work voltage of the
near floor sensor is 48V, the 63A breaker shall be closed and the K4 shall be plugged off (when testing non-near
floor logic it shall be plugged in), otherwise the near floor will not work.
7) Checking the logic movement at the non-near floor position
Switch on the 3-phase AC power supply, move the cage to the position with a distance about a half meter from
the opening door area by crawling, and resume the overhauling switch to normal position.
Then shut off the 3-
phase power supply, then the PLC shall make movements as the following sequence: Y2 lamp is on, a switching
command is generated; Y3 lamp is on, a testing command is generated; if the input point X2, X3 and X4 are on
(“BROKEN” means these lamps shall be on at overhauling, “PASS” means that these lamps shall be off at
overhauling), that means the safety, door lock and overhauling loops are normal; Y4 lamp is on, an emergent
operation command is generated. The green LED on the front panel of the ARD is on.
8) Setting up the velocity and moment of the ARD
⑴ There is a short circuit insert J1 on the motor driving board in the ARD. As the picture 13 shows. Please
notice that generally the moment has been adjusted when the product leaves the factory. Unless an abnormal
phenomenon is observed at the working site, please do not adjust the moment at will, in case a moment too
small may cause slipping, or too big current may burn the module.
⑵ There are four positions for JMP, as the sequence 1, 2, 3 and 4 marked out in picture 14. The velocity changes
from high to low. For 50Hz asynchronous motor, J1 shall be put at the position of 2 or 3; for low frequency
synchronous motor, J1 shall be put at the position of 3 or 4. It depends on an even velocity. Picture 13

9) Debugging emergent operation
Put the switch on the front panel of the ARD at OFF position, close 63A fuse, and disassemble Y1 terminal (see
picture 15), turn on the 3-phase power supply. Then put the switch on the front panel of the ARD at ON position,
shut off 3-phase power supply, the emergent operation shall be activated, and the elevator shall move upward in a
low speed (if the elevator moves downward or does not move, switch the equipment to the reaction’s power
supply phase order), and the door shall open when the elevator arrives at the door area. If the door does not open,
the door motor may be connected at a wrong direction, the polarity (DC) or phase order (AC) of the door motor
shall be switched.
10) Directional test
⑴ Repeat procedure 9), if the ARD moves upward with no load normally, the directional test can be made.
⑵The Y1 terminal on PLC shall still be broken.
⑶The elevator is with no load (or be loaded with about 40% of its rated load)
⑷Move the elevator to the upside of the middle floor, with a distance to the opening door area about a half meter.

⑸ Use small screwdriver to adjust the directional pot W1, as the picture 16 shows. Note do not adjust the W2!
⑹ Shut off the power supply to do emergent test. When the elevator moves upward, adjust W1 clockwise till the
LED L6 is on, and then adjust the W1 anticlockwise till L6 just off.
⑺ Repeat the emergent test, the L6 may flash at the startup but shall be off in the running, and Y1 shall also be
off. Then connect Y1 again.
⑻ If conditions are available, load the elevator with 60% of its rated load and do the test. If L6 is on at the startup,
PLC’s Y1 is also on, there is an output at Y1, and the elevator moves downward at emergent operation, then the
equipment is adjusted.
⑼ If the elevator does not move downward, or it still moves forward, or it cannot move, the W1 shall be fine
adjusted clockwise till the L6 flashes and there is an output at Y1, also the elevator shall moves downward, then
the adjustment is done. (When the elevator moves downward L6 automatically turns off)
⑽ Repeat the 40% loaded or no loaded test to see whether the elevator will move upward in emergent operation.
If yes, the adjustment is done; if no, it needs to be fine adjusted.
If your ARD is H or HB type, please make the following debugging.
11) Electric fault emergent operation debugging
If all above mentioned debugging are normal, switch on the overhauling switch to make the elevator at
overhauling status, power on the 3-phase AC power supply, close 63A breaker, move the elevator downward to a
position with a distance from the opening door area about a half meter by crawling, set a electric fault manually,
and then resume the overhauling switch to normal position.
About one minute later, the ARD starts emergent
operation and the elevator moves upward (the green lamp on the front panel of the ARD is on), and the door
opens automatically when the elevator reaches the opening door area.
12) Wireless call debugging
After the above-mentioned debugging, plug the accessory telephone into telephone line, the 3-pin plug of the
telephone shall be inserted into the 3-pin socket on the HB ARD. When the dialing voice is heard in the telephone,
dial the cell phone number or telephone number to be called, confirm everything is normal and hang

Maintenance Notice
the telephone, repeat procedure 8. When the elevator starts emergent operation, the telephone can automatically
dial the preset number repeatedly, and the cell phone of telephone be called can get ringing signal. After
debugging, all components and switches, which have been operated during the debugging process, shall be
checked to see whether they are in normal work status. If everything is normal, fix the cover of the ARD and the
battery box, and connect a protecting ground line to the shell of the cabinet. The code and meaning of PLC’s IO
terminals in the ARD are shown in table 9.

Maintenance Notice
WS420 ARD is maintenance free, but as a kind of rescue equipment for elevator, we also suggest a routine and
regular inspection of the ARD in terms of the following items for safety.
1）Battery Cell Volt Measuring
Check monthly whether the battery cell outputting is in the rated operating voltage. First, turn off the switch
which in the front panel of ARD, then cut off the three-phase AC power, and use the direct voltage at multi-meter
to measure the output terminal in the back panel of buttery. (see Figure 17) the volt of E1, E2 should be more than
or equal to 24V, and the deviation between E1 and E2 should be less than 1V. If it doesn't meet the two standards,
the battery cell should be changed (useful life of battery is 2-3 year). After measuring, turn on the three-phase AC
power, and then turn on the switch of front panel of ARD.
2）Charger Inspection
Inspect the charger of ARD every three months. In normal (state of electrifying)
working state of ARD and normal power supply of the three-phase AC power,
measure the voltage of E1, E2 with multi-meter. Their volt should be more than
E2
○
E1
○
○
+48V +24V 0V
25.5V (at lest more than the output (volts), and the deviation between them
should be less than 1V. If it meets the two standards, the charger works well.
Figure 17. Battery cell
3）ARD Operation Simulation
Simulate an operating of ARD in every six months. Simulation will be done in state of normal power supply of
the three-phase AC power. First stop the elevator at half a meter away from the gate region, and put the inspection
switch in normal state, then cut off the three-phase AC power. Here the green light of front panel lights, and the
elevator door can open automatically when up to the gate region. The simulation ends when green light goes out,
again turn on the three-phase AC power, and if the red light lights, the ARD works well.
Note:
When doing the routine inspection, users should turn on the inspection switch, then the ARD will locked and
refuse to move. And for the safety of the inspectors, you'd better turn off the switch in the front panel of ARD,
(thus, in any case, the ARD will not operate). Remember that, after the maintenance and inspection, you must turn
on the switch of ARD.
